This says the Line Gain on the K3 is too low. Or the PWR slider on the
WSJT right side is too low. Be sure in the F2 menu / Settings, the
Audio panel has the correct Audio IN and Audio OUT selected under
Soundcard. Should be USB CODEC.
Don's info is very correct and very complete. Don't pay attention to
what others advise unless they have a K3 or K3S or KX3. Their advice on
audio levels will be incorrect as the Elecraft radios handle audio and
power quite differently the JA radios.

When I click the tune button in the FT-8 software, the K3
goes into transmit but there is no RF out.

My KX3 cuts off input if the mic gain is set too high. Maybe same issue for
your K3?

Larry,
FT-8 is no different than any other data mode, so if other data modes work look
carefully at the FT-8 computer setup.
One thing I can say is that you must have 4 bars of ALC showing with the 5th bar
flickering. If you have no indication on the ALC meter, that means the K3 is not getting
enough audio from your software application, and you will have to find out why - perhaps
the "power" slider in the
FT-8 application is set too low.
You might want to take a look at the data mode setup on my website
www.w3fpr.com. In the left column scroll down to the last entry and click on
it to get to the article.

Group,
I am unable to get my K3 to TX any RF when set up for FT-8.
Hardware is K3, Behringer U-phoria UMC202HD USB sound card running on
WIN XP with most recent version of WSJT-X software. FT-8 settings
Radio
Tab: baud 38,400, data 8, stop 1, handshake none, PTT CAT, Mode
data/packet, split none. Tests of CAT and PTT are both successful.
Soundcard tab is set for the Behringer card.
Soundcard is cabled to LIne In, Line Out on K3. I am in Data
A
(USB) mode. K3 Menu Mic Sel is set to line in/line out. Waterfall
displays signals and they decode properly.
When I click the tune button in the FT-8 software, the K3
goes into transmit but there is no RF out. When I press the tune
button on the K3 I do get RF out. When we briefly attached a
headphones plug to the soundcard out lead that had been connected to
the K3 line in we could hear the tuning tone when clicking on the tune
button in FT-8. I do AFSK RTTY without difficulty so I do not think
the line in jack is faulty.
Ideas, please.
K4KGG, Larry
